Most pitchers develop several main pitches and then throw variations of those pitches.

Here are some tips for throwing the knuckle curve, split finger, circle change and knuckle ball:

• Middle finger on seam
• Point of index finger on other seam
• Delivery pitch with wrist “cocked”
• Ball behavior: same as curve ball, but faster than the regular curve ball and slower than the slider
